I have tried to get my followers to use the Pillar of Sacrifice both for Boethiah's Calling and to upgrade my Ebony Blade, but the ones I've tried so far haven't worked.
- Onmund, College of Winterhold
- Cosnach, Silver-Blood Inn
- Recorder, Recorder Standalone mod
- Marcurio, The Bee and Barb
These 4 would just face me and say something like "Got it." but not touch the pillar. Then I tried telling Sofia (also a mod) to use it, but she never even activated the floor to glow in the first place. I'm sure it is just a glitch concerning my mods, but I don't know how to show my full mod list because I have downloaded mods through the ingame Mods option AND from Nexus using NMM, and I don't remember the directories for either of them. I have Skyrim SE and USSEP.
I have also referred to this article but it did not help me.
